Database Management Systems (DBMSs)

Lists supported and tested DBMSs along with the Visual COBOL features that use them.

All RDBMS testing is done on both 32- and 64-bit platforms based on RDBMS client software availability.

With regard to support for each of these third-party RDBMS supported version, Micro Focus :

  • Provides support until the standard end-of-service (EOS) date provided by the RDBMS vendor
  • If your deployment requires support for a given RDBMS beyond the vendor's EOS dates, check with Customer Care for availability of Extended Support Plus options.
  • Encourages you to include third-party RDBMS consideration when planning an upgrade to your Micro Focus product

With regard to resolving reported issues with Micro Focus software while using a third-party RDBMS, Micro Focus :

  • Attempts to resolve issues for supported DBMSs on tested or untested platforms
  • Investigates issues involving planned but not yet supported RDBMSs, and attempts to resolve non-architectural issues that also occur in the latest supported RDBMS version

This version of Visual COBOL supports the following Database Management Systems:

COBSQL (Pro*COBOL)

Before deploying a COBSQL application, be sure to install and configure all applicable third-party software.

Note: COBSQL (Pro*COBOL) is supported for native COBOL only.

XA Switch Module
When the Enterprise Server feature is enabled, the Oracle XA switch module is provided for COBSQL (Pro*COBOL), and is available on the same platforms as are indicated in the Availability section above. Oracle Instant Client fully supports all 1PC functionality with Pro*COBOL applications.
Restriction: The Oracle Instant Client does not support the 2PC functionality of the Oracle XA switch module. To use 2PC functionality with Pro*COBOL applications, you must install Oracle Client, not Instant Client.
Certification of RDBMS Precompilers for Native COBOL
Certification of RDBMS precompilers with Micro Focus products is the responsibility of the RDBMS vendor, rather than Micro Focus. Certification information can be found within the relevant Oracle documentation. If you have an Oracle MetaLink account, document # 43208.1 provides details of all language compilers certified by Oracle for use with their precompilers.
Preprocessors
COBSQL supports the following database preprocessors:
  • Oracle Pro*COBOL versions 18c and 19c database preprocessors
  • Sybase Open Client Embedded SQL/COBOL Version 11.1 or later
  • Informix Embedded SQL/COBOL Version 7.3 or later
Compiling
On x86 and x86-64 platforms, when compiling with COBSQL for use with Oracle, do not use the COBSQL directive option NOMAKESYN, since this directive results in COMP host variables, and on Intel platforms these are incompatible with the native byte order expected by Oracle.
Testing
For this version, COBSQL was tested with Oracle Pro*COBOL versions 18c and 19c.
Executing
On HP-UX, to execute an application precompiled using Pro*COBOL (or COBSQL) after you have created a callable shared object of Oracle DBMS routines, you need set an environment variable, LD_PRELOAD, to point to the Oracle client callable shared object, for example: 
LD_PRELOAD=$ORACLE_HOME/lib/libclntsh.so       
export LD_PRELOAD

A script is available that creates an executable run-time system or a callable shared object containing Oracle support (applies to UNIX environments only). You can find the script in the Micro Focus Knowledge Base article titled Building and executing Pro*COBOL applications on UNIX.

Certification of RDBMS Precompilers for Native COBOL
Certification of RDBMS precompilers with Micro Focus products is the responsibility of the RDBMS vendor, rather than Micro Focus. You can find IBM document certification information for DB2/COBOL applications within the IBM Information Center for DB2, in the topic Support for database application development in COBOL.
Preprocessor
DB2 ECM supports the following database preprocessors:
  • IBM DB2 LUW Version 10.5 or later
  • IBM DB2 Connect Version 10.5 or later
Testing
For this version, DB2 ECM was tested with DB2 LUW 10.5 and 11.1, and 11.5

OpenESQL

The PostgreSQL switch module (early adopter program) is available on the following UNIX platforms:

  • x86-64 running Red Hat Linux
  • x86-64 running SUSE Linux
Native COBOL
  • OpenESQL supports access to relational databases using ODBC 3.0-compliant drivers
  • Refer to your driver vendor's documentation to determine whether your driver is suitable for use with OpenESQL
JVM COBOL
OpenESQL supports access to relational databases using JDBC 4.0-compliant JDBC drivers. The following table shows the tested DBMSs and their corresponding JDBC driver filenames:
Tested DBMS Versions JDBC 4.0 Compliant Drivers
DB2 LUW 10.5

DB2 LUW 11.1

DB2 LUW 11.5

db2jcc4.jar (and db2jcc_license_cu.jar)

Microsoft SQL Server 2017

Microsoft SQL Server 2019

sqljdbc4.jar2
EDB PostgreSQL 10.5 and 11.x postgresql-42.0.0.jre7.jar
1Some Oracle JDBC drivers are distributed as .zip rather than .jar files.

2 On Windows platforms, if you are not using Windows authentication, no additional resources are required. However, if you are using Kerberos authentication with a driver version of 4.0 or later, although integrated authentication is not required, you might need to follow additional configuration steps as described in the driver documentation. No additional resources are required for UNIX platforms.

To use JDBC DataSource Objects, you must also install and configure a JNDI server.

  • If you are using a Java application server, it includes a JNDI server you can use to configure DataSource objects. This process is described in the Java documentation for the application server.
  • If you are not using a Java application server, or if you require a standalone JNDI server to configure DataSource objects for initial evaluation and development, see the To install and configure Simple-JNDI topic in this documentation set for instructions on downloading, installing, and configuring the open source JNDI server Simple-JNDI for this purpose.
